Reference of Wabra Contractor, Zahran, Kingdom of Saudi Arabia

By here with we WABRA CONTRACTOR EST note that during the cooperation with the company EKOTON it has acquired a reputation as the organization of highly professional specialists, which knows subtleties of the operation of wastewater treatment facilities and develops technologies of the highest world level. We, as main contractor, are glad to work with products that are manufactured at this enterprise.

In July 2016, 2 ZSP sludge scrapers with the diameter of 10+8 m were delivered, installed and put into operation in wastewater treatment plant 1500 m3/day for Air Forces Defense in Zahran, Kingdom of Saudi Arabia.

All installed equipment has been operating stably and smoothly from 2016. One of the main advantages of this type of equipment is the serviceability and reliability, Sludge scrapers are structurally designed for a long-term trouble-free operation. No wear of moving parts are observed.

The suggested design is proved to be stable, rigid and reliable in operation. Bridge on the sludge scrapers has central drive and mounted on two independent supports that are placed out of the clarifiers. Such construction allows not carrying and weight on GLS tank where scrapers must operate.

The cleaners of walls and edges of sludge scrapers are well designed, convenient in adjustment and don’t cause dissatisfaction. All the electric part of the drive runs smoothly in various temperature conditions.

WABRA CONTRACTOR EST thanks the team of EKOTON for the high quality equipment and careful attention to the needs and requirements of our enterprise during the production, delivery and adjustment of sludge scrapers.

Reference letter Equipment: Multi-Disc Screw Press MDQ-353C EKOTON

Location: WWTP, Sechin, Hungary
Start-up date: December 2014

Since the Multi-Disc Screw Press MDQ-353C was launched by EKOTON Industrial Group, the equipment performance is faultless, it works stably and without interruptions. During the operation of the equipment it turned out that:

  • inlet sludge with dry solids content of 1% after the EKOTON dewatering Screw Press, becomes of 18-22 % while ensuring compliance with the filtrate quality regulations;
  • the equipment works completely in the automated mode, the control cabinet is equipped with a touch screen by means of which it is easy to set the operational parameters not only of the dehydrator, but also of the sludge pump;
  • the equipment works stably in automatic mode, without the need of operator intervention during operation; the equipment works noiseless;
  • the equipment works reliably and flawlessly: within 3 years of operation, only flexible hoses for rinsing water have been replaced.

Since two Multi-Disc Screw Presses MDQ-353C were launched by EKOTON Industrial Group, the equipment performance is faultless, it works stably and without interruptions. Discharging the cake from dehydrators takes place by screw conveyors also produced by EKOTON. During the operation of the equipment it turned out that:

  • inlet sludge with dry solids content of 1 % after the EKOTON dewatering Screw Press, becomes of 18-20 % while ensuring compliance with the filtrate quality regulations;
  • the equipment works completely in the automated mode, the control cabinet is equipped with a touch screen by means of which it is easy to set the operational parameters not only of the dehydrator, but also of the sludge pump and screw conveyors for cake transporting;
  • the equipment works stably in automatic mode, without the need of operator intervention during operation; the equipment works noiseless;
  • the equipment works reliably and flawlessly.

Case Study: Fish Processing Plant (Santiago, Chile)

In 2017 the dissolved air flotation complex for local wastewater treatment of fish processing plant in Los Lagos region had been installed by our partner Aguas Sipra S.A., including such equipment:

  • Fine drum screen RMB TP 6/6,
  • DAF unit FT-25,
  • Tubular flocculator,
  • Saturation system for white water preparing,
  • Pumps for the complex,
  • Automation system for the complex, including control system with sensors.

Ekoton DAF-Unit Flotator

Ekoton DAF complex has customized design for the particular application. The object’s features required high amounts of dissolved air to be fed into wastewater to tackle high loads of contaminants. The complex’s capacity is 18 m3/h.

The efficiency of the complex is as follows:

Los Lagos, Chilie Project Data

ParametersInput concentration, [mg/L]Efficiency, [%]Output concentration, [mg/L]
Total suspended solids (TSS)6,54195327
Biochemical Oxygen Demand (BOD5)10,696406,418
Nitrogen, Total Kjeldahi (NTK)72620581
Oil and Grace (O&G)9759098
Dissolved solids (DS)816032

In the result the customer got specially designed wastewater treatment system which is fully solves effluent requirements. In this project Ekoton confirms advantages if it’s developed DAF technology, as well as appropriateness of approach to use just the highest quality components available. Equipment operates steady well, which is really important for such a distant projects.

 

Reference of WWTP, Herzliya, Israel

During reconstruction of sewage treatment facilities in Herzliya in 2009 a new biological reactor, consisting of three sections of 6000 cubic meters each with an operating height about 6 m, was installed. Air is pumped by means of three air blowers of 6000 cubic meters each through disc diffusers.

Soon after launching it was obvious that all system is highly uneconomical. In order to keep oxygen concentration at 1.5/2 mg/l we had to continuously work with two-three air blowers (9000-13000 cubic meters) for the whole reactor and it was not always possible. After in the beginning of 2013 rupture marks were detected on some diffusers we decided that it is time to replace them by somewhat more effective. We issued a tender, and one of many offers we have received for consideration contained information about aerators of EKOTON Company.

There were a lot of cons: unknown company, lack of experience of work in Israel, disagreement of designers and technical advisors.

However, despite of some concerns and doubts we decided to install these particular aerators. This product attracted us by its simple and reliable design, price, mechanical strength, longevity, 8-year warranty, no need for service checks, easy and quick installation, and also a very tempting offer of company management: possibility to pay the most part of the amount only in case if we are fully satisfied by their operation, which can be done even in six months.

In November 2013 we launched the first section of the reactor with EKOTON tubular aerators.

Reality has exceeded our most optimistic expectations. Quantity of used air has significantly reduced as well as quantity of consumed energy.

Saturation of liquid with oxygen has become more stable and homogenous in the whole basin. In 2 months instead of previously agreed 6 months of observation of aerator performance it was decided to replace diffusers installed in two remaining sections by EKOTON aerators, which was done in stairstep order.

Today the whole reactor (3 sections) is functioning with installed EKOTON aerators, and we are extremely satisfied with obtained results. Required oxygen concentration (about 2 mg/l) is kept in all sections with much less energy consumption. The most part of a day (14-16 hours) we use one air blower (4500 cubic meters) and during peak hours (8-10 hours) two air blowers (instead of 2-3 air blowers used previously, before replacement of aerators). I send you the reactor operation schemes made before and after replacement of aerators.
