ENTA Treatment Systems Engineering Contracting Corporation products

The control of the flows in the canals at the water and wastewater treatment plants is performed by the penstocks. ENTA produces penstocks assembled to the canal by its own design as being rectangular shape and from the material of carbon steel or stainless steel. Impermeability is provided by the use of P,V and double-lipped rubber seals beside the three sides of the penstocks. Also there is performed the special designs for the structures and special penstock production as proper to the demand.

Wall type penstocks are used to control the flows in the tanks at the water and wastewater treatment plant and to provide the isolation. At all designs of ENTA especially the impermeability is provided by the use of the P,V and double-lipped seals besides the four side of the penstocks and for 1 m seal length (at the pressure of 5 m on seat or 4 m off-seat), there is reached to the very low impermeability values as 0,4 liter/min. The wall penstocks have a wide size range and are designed specially as per the pressure applied and the distance to be closed.

Adjustable weirs are mostly utilized for level control. The main feature that sets them apart from sluice gates is that they allow partial opening control. Furthermore, they may be opened downwards or in angles, as the main purpose is controlling the water level, as opposed to sluices gates that usually open upwards.

Telescopic valves which are assembled on the pipe, control the water inlet according to the water level inside the tank. These are preferred at the deep canals. Our manufactures are designed as stainless or carbon steel.

This is the most widely used screen model as fine and also coarse screen at the large and medium sized treatment plants. These can operate at very deep canals as per the demand and without being any limitation of the canal height The main application areas are domestic and industrial wastewater treatment plants, lifting stations and water treatment plants. Linear mechanical screen is a mechanical equipment which is assembled to the ground of the canal with an angle of 750° and cleans the bar screen by combing vertically.

Internal flow drum screens (IFD) which are produced for screening of the solids prone to settling, are in the group of fine screens. IFD; is a drum made of perforated metal sheet or mesh screen wire and consists of a bearing system, water distribution weir and water spray mechanism. By its fully closed structure, some problems like odor, spring etc. completely prevented. Screens are made from the material of stainless steel, epoxy painted or galvanized cover carbon steel. Screening ranges change between 10-80mm, and screen hole diameters change between 250pi-2mm.

Material Body: AISI 304, st-37 + Epoxy Drums: AISI 304 SS304, Chassis can be produced as St37 or SS304 or from any other material as appropriate to the project. Impellent group: Motor + reducer , if required, variator or frequency converter can be added. (Optional) Scraper Knife : The part of the AISI 304 stainless steel scraper arm which touches to the surface of the drum, consists of a bronze knife which is installed with bolts. In order to increase the press of the knife on the surface, it has a structure which can be arranged with an opposite weight.

The cable operated bar screen is fully automatic cleaning equipment. It can be used in the inlet channel of pumping station, wastewater treatment plant, power plant and desalination plant for the floating matters screening or bottom accumulation removal.

External flow drum screens (EFD) which are produced for screening of the solids prone to swimming, are a kind of fine screens which are used at domestic and industrial wastewater treatment plants and also are safely used at the process wastes of the industries like leather, food, paint, textile, paper, sugar etc. These screens operate by collecting the screened material at the external surface of the drum. This screen drum is gained by the wires with V sections wrapping as spiral by a special device and welding with high frequency.

Static screen is a fine screen equipment which has a self-cleaning and can make screening by the gravity without needing any impellent group. Static screens (STS) especially used in the wastewater treatment plants of the industries like textile, paper, food, alcohol. This equipment consists of a water distribution weir and a screen system which is made from stainless steel wires with V section. The usage of this equipment is very easy and almost does not need any maintenance.
