Treatment Plant Equipments

SLUICE GATES

Sluice gates which are used in water and waste water treatment plants offer a wide range of driving unit and material options. Perennial and easy to use sluice gates are manufactured which will assure the impermeability. We can group the sluice gates into two according to the application areas.

 

We offer a wide range of models for sluice gates which can be mounted to the wall or to the channel varying from manual or electric driven to pneumatic types. We produce sluice gates in different dimension. The thickness of housing and frame of these sluice gates are calculated conforming with the water pressure. Depending on your preference fixed or rising spindle opening closing devices are available.

GRID CLASSIFIERS

The incoming material is pumped through the inlet to the grit classifier. Grit and similar materials are sedimented to the bottom by a horizontally moving bridge. Depending on the number of the collecting channel used in the project, number of grit classifiers may vary. They can be produced of aluminum, steel, stainless steel and galvanized steel.

 

Grit scrappers are used to sepa-rate sand, grit and similar inorganic ma-terials from waste water to prevent equipments of dete- rioration and con-gestion of sedimen-tation tank. This unit might not be needed for treatment of the indust- rial waste water which doesn’t contain these above mentioned particles.

 

Grit scrappers are used to hold the particles which have a density superior to 2650 kg / m3 and a diameter superior to 0,1 – 0,2 mm. The sedimented sludge are collected and rotated by water flow and discharged by the appropriate pump through outlet.

 

The waste water which is pumped from the grit scrappers are collected in the grit classifier unit. The driving unit, rotating spirally, discharge the sedimented sludge to a container located at the outlet.

MECHANICAL SCREEN

Overall ineffectiveness of treatment facilities decreases by right operation of appropriate mechanical screens. Determining of appropriate screens not only depends on characteristics of the waste water but also depends on hydraulic calculations and topographic structure. We are enhancing our screen portfolio in order to offer solitions for customer’s requests. All of the mechanical screens can be automatically operated in water level difference or adjusted time intervals.

 

These are the type of screen most widely used both as fine and coarse screens in large and medium scaled treatment plants. They function even in the deepest channels without any limitation for channel height. Linear mechanical screen is a mechanical equ- ipment mounted to the channel base at 75° angle, with rakes that clean the screen bars in vertical direction. In general, it consists of a frame, a fixed screen, a scraping system and a waste container.

CIRCULAR SCREENS

Circular screens are effective equipments which are used for removing solid materials from waste water flow. Generally, screen consists of rake system, motor redaction group and rake cleaner unit. solid materials are scrapped from the channel bottom upwardly by the circular moving rake cleaner. Screen cleaner arm that is located on the of the channel flops the solid materials drifted by rack to the dustbin.

STATIC SCREENS

Static screens are the self cleaning fine screening sieves which are capable to screen with the help of gravity without an actuating equipment. Static screens are applied especially in treatment plants of industries such as textile, pulp and paper, food processing and alcohol production.

 

Static screens which are produced of V – notched stainless steel wedge wires consists of a water distribution weir. These sieves are characterized by their easy operation and minimum maintenance requirements.

ROTARY DRUM SCREEN

Externally Fed Rotary screens are fine screens which are produced for screening floating solids. These screens are used in domestic and industrial waste water treatment plants as well as process wastes of industries such as textile, pulp and paper, food processing and alcohol production. The screened materials are collected on the outer surface of the rotary sieve which is produced through a high frequency welding of V- notched wires spirally coiled with a special device. Thanks to this notch provided, clogging of the screens is almost impossible and permeability rate is very high.

 

The wastes which are collected on the outer surface of the rotary sieve and can be scrapped by a scrapper blade and are discharged either to a waste contai-ner or directly to the conveyer system. A pressurized water spraying system is present against any probable congestion.

FILTER PRESS

The filter press is the most efficient solid/liquid separation system. It is the most popular filtering process in all kind of applications. The fields of application of filter presses of the plate and frame, chamber and membrane types are extremely varied. The other factors indirectly affecting its capacity are:

* Fast cake discharge by automatic plate shifting device
* Time saving in cloth cleaning by automatic washing device
* Short cycle times for closing and opening of the filter press
* Service requirements of the plant are low and its main- tenance is easy due to the high quality material utilized. Our filter presses are not only used for dewatering of sewage, industrial wastewater and water sludge but also used in wide applications in process industries.

Some major industries are:

1- Chemical production
2- Mineral processing
3- Production of soap fat and wax
4- Sugar beet
5- Color pigment and dye
6- Paint
7- Oil, grease and plastic
8- Ceramic recovery
9- Beer, spirit, wine and yeast
10- Phosphate binding bath

BELT PRESS

Belt filter presses have been an economical dewatering method especially in applications with a high sludge flow rate owing to their continuous operation principle. We manufacture various types of belt filter presses for all type of sludge content and level of dewatering. The robust frame and drum of our belt filter presses are torque resistant.

 

They are main-tenance free because of all bearings are waterproof and wear resistant. While maximum cake dryness is obtained by different pressure levels, the solids content of the filtrate is very low. Belt washing is very efficient owing to self-cleaning type nozzles, which affects the efficiency of belt filter presses positively

SURFACE AERATORS

They are used for aeration and mixing of biological reactors. They provide high oxygen transfer in waste water. The simple mechanical structure consisting of actuator, shaft and fan allows easy operation. It can either be easily mounted on fixed bridge or be attached to the side of the basin with a special barge system in case where water level is changing. Depending on the motor power 18 dif-ferent models are produced between 1,5-132 Kw with different capacity and fan diame-ter variation. In case where the basin geo-metry is un-suitable, they may need to be accessorized by some equipments such as suction pipe, suction nozzle and baffle

SCRAPERS

It’s possible to group the circular scrappers in different ways. As per the driving type, they can be classified as central driven, fixed bridge scrappers, peripheral driven and rotating bridge scrappers. The length of the rotating bridge scrapper can either be equal to the basin diameter or any fraction of the basin diameter. The solid load of the treat-ment plant determines the method of sludge disposal. The sludge which sediments at the bottom can either be scrapped into the sludge funnel or be pumped to the pipeline of the central structure b suction pipes. Numerous options can be proposed for both method. The selection of scrapper is another issue and the options we provide include panel, cage and profile or pipe construction.

FLOCCULANT PREPARATION UNITS

In this unit; preparation and dosing of polyelectrolyte is provided. There exists, fully automatic powder polyelectrolyte feeding, solution preparation and dosing. Powder or granule polyelectrolyte must be transformed to solution before usage. Polyelectrolyte’s usage area is chemical treatment systems, sludge dewatering, before belt filter press and filter press.
