Menashe 2



In 2011, Menashe was asked to prepare a plan for regulatory compliance to new irrigation standards requiring tertiary treatment and full nitrification and denitrification. The Menashe 2 WWTP upgrade included four different phases of construction:

  • Phase A. Effluent polish treatment system
  • Phase B. Pre-treatment system
  • Phase C. Aerobic system upgrade
  • Phase D. Disinfection system

In 2013, Triple-T was selected for Project Phase A, which was successfully completed in 2014. In 2016, Triple-T was once again selected for Project Phases B & C, in order to implement its patented TAYA 2.0 system, designed for secondary treatment and full nitrification / denitrification. Menashe selected TAYA 2.0 technology, due to the low lifetime costs from energy savings, sludge minimization and operational simplicity, as demonstrated through TAYA’s application as the effluent polish system at Menashe (Phase A).

This project received special funding and promotion from the Israeli Water Authority, due the TAYA 2.0 innovation, which combined the process advantages of the original gravel-based TAYA 2.0 system with specialized plastic media, enabling high-strength wastewater treatment and cost-effective sludge handling.


The design of Phases B & C, includes the following treatment elements:

  1. Screening: Design of pretreatment system including 6 mm screens, grit removal and fat trap.
  2. Gravitation Settling: Design of primary sludge settling.
  3. TAYA 2.0: Two TAYA 2.0 systems operating in parallel or in a row, designed for primary aeration and full nitrification and denitrification.
  4. Secondary Clarification: The exiting clarifiers will be leveraged to remove any excess sludge from the TAYA 2.0 systems, without recirculation.


Triple-T’s TAYA 2.0 system provides Menashe with a robust, flexible and energy efficient solution to its wastewater challenges. An economic assessment of Triple-T’s TAYA 2.0 system, conducted by Menashe and Triple-T, estimate an annual cost savings in excess of $130,000 / year, based on the following benefits: 

  1. Low energy consumption: 80% less than the existing system
  2. Low sludge production 50% reduction in the excess sludge
  3. Lower O&M: As a result of less electro mechanical equipment and less sludge handling.


Piggery Pilot 


In animal farms such as dairies and piggeries the slurry is screened and then spread onland as a fertilizer. The limiting factor is the TN quantities over the year. The farmer chosen solution is an optimization between the cost of treatment, the cost of spreading the slurry and the size of land available. One common thing for all farms is the need for nitrogen reduction alongside with the need for a simple system to operate. With the above in mind Triple T has developed a unique solution to meet these needs. A TAYA system based on plastic media. The TAYA-II Plastic system is an aerobic-anoxic, fixed film technology, extremely efficient in energy consumption ‘less than 15% of the energy consumption needed for intensive biological treatment, and in minimum excess sludge production. It is designed to reduce the TN concentrations as the main focus but sharply decreases, BOD, COD, and TSS concentrations as well.


For the last 18 months, a TAYA-II pilot plant is being operated at Triple-T R&D laboratories. The pilot treats Piggeries wastewater after a solid separation unit.

The average capabilities of the system are as follows:

La Falcheta Farm 



TAYA II is an innovated wastewater treatments system designed to meet the needs of the agricultural market. It's an aerobic-anoxic, fixed film technology designed to reduce total nitrogen as the main focus. TAYA-II is designed to meet the specific requirements of the piggeries and cow farms from a wastewater treatment plant. Emphasis is given to the ease of operation, low energy consumption, low biomass production and low maintenance.


Currently a demonstration plant is placed in La Falcheta farm (near Torino). The farm has an anaerobic digester fed mostly with cow manure and corn. The effluent of the anaerobic digester (TS 5.6%) is fed to the TAYA II system a0er a 0.5 mm solid separation unit.

The La Falcheta system demonstrates under real conditions the capabilities of the system to handle agricultural wastewater. The ease of operation, minimal electro-mechanical equipment and low biomass production are clearly demonstrated.

Kibbuts Lahav 2



In 2014 Kibbutz Lahav hired Triple-T to design and construct an upgrade to its existing WWTP, in order to meet the following professional objectives:

  1. Increasing effluent quality, to meet the irrigation regulations.
  2. Increasing capacity to handle additional flow from nearby settlements.


The upgrades of the existing treatment plant at Lahav included an addition of a 6 mm rotary screen, extensive settling and anaerobic digestion of primary sludge and anoxic-aerobic treatment using Triple-T’s patented TAYA system. This design took advantage of existing infrastructure available on site, in order to minimize capital investment. This was accomplished by converting an existing lagoon into an anaerobic pond, along-side a newly constructed basin. The existing TAYA system was upgraded by simply increasing the volume of the gravel media inside the basin, in order to expand capacity to take on additional flow from nearby settlements.


Since 2015, the new TAYA system has produced consistent effluent quality in accordance with the strict environmental standards for Israeli wastewater reuse, using 80% less energy than activated sludge, and 80% saving in sludge treatment cost. Most importantly however, Kibbutz Lahav benefits from a robust treatment system, requiring a local operator only once a week, due to the minimal electro mechanical equipment and low requirements for sludge handling.

Of Hanegev 



In 2011, Triple-T was hired to design and support operations of an upgrade to the wastewater treatment plant at Of Hanegev, one of the largest poultry processing factories in Israel.

The wastewater from the plant consisted of two complex streams, one from the abattoir and the other from the rendering process, each containing high levels of organic matter, suspended solids, fats, oils and total nitrogen. The wastewater effluent from the upgraded treatment plant at Of Hanegev required treatment to a tertiary level, including disinfection, for irrigation purposes.The treatment plant is designed to meet the stringent requirements of the Israeli Health and Environmental Authorities, while handing a heavy hydraulic load of 0.6 MGD.

Triple-T designed a full-scale solution to expand the facility’s treatment efficiency and to produce higher quality effluent.


The design of the upgraded WWTP at Of Hanegev included the following treatment elements: Existing Pretreatment including solid separation, DAF and centrifuge.

The upgraded system included solid separation, extensive anaerobic treatment and equalization, anoxic/aerobic treatment using Triple-T’s patented TAYA system as well as sand filtration and chlorination.

The TAYA system was designed to handle the remaining organic matter in the wastewater stream as well as full nitrification and denitrification, before discharging to the tertiary sand filtration and disinfection.


Triple-T’s unique configuration combining extensive elements (earth basins and passive aeration in the TAYA) with intensive biochemical processes provides its client with stable and cost-effective wastewater treatment solution. The core component of this treatment plant, Triple-T’s TAYA system, provides Of Hanegev with unprecedented level of process robustness, previously unavailable with the earlier wastewater treatment system. TAYA provides Of Hanegev with a barrier against upstream process changes inherent in the client’s operations, by ensuring cost-effective nitrification and denitrification in variable loading conditions.

The benefits of the system can be summarized as follows:

  1. High Performance: The TAYA system allows highly efficient nitrification-de-nitrification processes for the high levels of ammonia and TN concentrations.
  2. Energy Efficiency: 80% energy reduction compared to activated sludge
  3. Sludge Reduction: 80% reduction in sludge production and handling, compared to activated sludge.
  4. Process Robustness: Capable of managing fluctuations in loading, producing consistent quality effluent in line with stringent environmental regulations.


Ramon AFB 


The Park at Ramon Air Force Base is irrigated with effluent from the WWTP based on TAYA technology. Triple-T is the proud designer, constructor and operator of this plant located in the heart of the Negev dessert, since 2011. This project was established in collaboration with the Jewish National Fund and the Israeli Air Force.


The effluent discharged from the Ramon Air Force Base was required to be treated to a tertiary level with disinfection, for unlimited irrigation purposes. Once treated, the effluent are recycled back to the base, for irrigation of the JNF’s Essence of Life Park.


Triple-T selected TAYA due to its low lifetime cost, ease of operation, low-energy process, and treatment ability. After primary screening, the wastewater enters into two sequential settling ponds, for primary sludge settlement and anaerobic treatment. The wastewater then passes into Triple-T’s proprietary TAYA system where the majority of the containments are removed. 

Today this facility serves as a model example of an decentralized, low-cost wastewater solution, while achieving very high effluent quality

In 2006 Kibbutz Shomria's population increased dramatically in size due to the acceptance of new members from the nearby community of Gush Kaf. This influx of inhabitants prompted the Kibbutz to search for a cost-effective decentralized wastewater solution for its wastewater, instead of pumping the wastewater away to a centralized facility and buying fresh water.

In 2008, the kibbutz selected Triple-T to design the aerobic stage of its wastewater treatment plant. This system needed to be capable of handing a mixed stream composed of wastewater from the municipality, dairy farm and a nearby army base. This solution would replace Shomria’s existng wastewater plant consisting of oxidation ponds, which consumed enormous amounts of land.

After conducting a technology assessment, in which Triple-T compared the performance and economics of various different treatment systems, the Kibbutz selected TAYA due to its low lifetime costs, ease of operation and treatment ability.


The design of Triple-T’s treatment plant for Shomria consisted of the following elements: Two anaerobic settling ponds, two aerobic TAYA systems, and a final reservoir to collect the treated effluent. The treatment plant is constructed on the side of a hill, so the wastewater flows from each stage of the process to the other using only gravity.

Triple-T TAYA’s system was designed to provide Shomria with a robust, flexible and energy efficient local solution to its wastewater challenges. The benefits of the TAYA can be summarized as follows:

Local Solution: TAYA treats the wastewater locally,
saving the client considerable amounts of money to treat the wastewater and purchase clean water re-

  1. High Performance: TAYA is a proven technology for secondary treatment, due to its high aerobic treatment capabilities
  2. Land Savings: TAYA provides the client with substantial land savings compared to other more extensive solutions like oxidation ponds and traditional wetlands.
  3. Low Energy Consumption: TAYA’s patented pumping arrangement minimizes the consumption of energy, only 10-20% of Activated Sludge.


Over the last three years, the TAYA system has provided Shomria with a reliable means of treating their wastewater, while preserving their land and significantly reducing their operational costs to 25% of conventional wastewater treatment plants.

Kibbuts Lahav  


In 2007, Triple-T was engaged to design and construct the retrofit of an existing wastewater treatment plant at Kibbutz Lahav, after the original system built in 2005 failed to comply with existing discharge requirements. Triple-T designed a solution to treat a complex wastewater stream from the piggery, abattoir, meat processing facility and the Kibbutz. This effluent contained high loads of organic matter and ammonia equivalent to a city of 25,000 inhabitants. The effluent discharged from the Kibbutz needed to undergo secondary treatment including the reduction of ammonia, to allow the effluent to be used for irrigation purposes.

After undertaking a two-year feasibility study, Triple-T constructed a full-scale solution using its TAYA technology to expand the facility’s capacity and increase its treatment capability.


Triple-T’s retrofit design maximized the use of the existing WWTP infrastructure, while reducing the overall land consumption by 60%. The three anaerobic basins continued to be used for selling and digestion, while two of the existing wetlands were converted into Triple-T’s TAYA system. The five remaining wetlands were not needed in the process.
