Optional equipment for settling tanks

The ECOTON Industrial Group offers a range of optional equipment for primary and secondary settling tanks to improve the efficiency of wastewater treatment. ECOTON settling tank equipment can be supplied initially with the elements listed below, or it is possible to upgrade equipment already in operation at the site. The latter option allows not only to improve treatment performance, increase equipment reliability and reduce the need for maintenance, but also to reduce capital expenditures inevitable in the case of complete replacement of equipment.

Additional equipment for primary and secondary settling tanks EKOTON:

Four-wheel drive cart

Four-wheel drive cart provides high reliability and stability of settling tank operation at any time of the year. The use of four-wheel drive carts improves traction, facilitates winter operation and avoids slippage.

Motorized or electrically driven wheel

An energy efficient solution to reduce operating costs (lower energy consumption due to low motor power of only 0.37 kW, low oil consumption). This improvement ensures equipment reliability in harsh operating conditions (low and high temperatures, high humidity, dust, lack of space, etc.) and is characterized by compactness, ease of maintenance and high durability.

Centralized sump drive

The central drive provides movement of the working part of the sump (openings) without slippage (slipping) in winter period. The use of the central drive allows to refuse from the slipformer and drive cart and reduces the cost of cleaning the sump treadway. This equipment is easy to operate and requires minimal attention from maintenance personnel. The use of a centrally driven design is the most rational solution in cases when it is planned to install sewn fixed slabs to reduce the spread of odor from the open surface of the settling tank, as well as for tanks (reservoirs) made of steel, when the design of the sides of the settling tank does not allow the use of sludge scrapers with a peripheral drive.

Clarified water trays with toothed overflows

A solution to improve wastewater treatment quality and reduce operating costs. In the operation of a clarifier, it is important to ensure uniform movement of radial water flows to create the most favorable settling conditions possible. Toothed overflows allow to distribute the hydraulic load evenly along the entire length of the catchment flume and thus eliminate zones of intensive overflow, which lead to increased removal of suspended solids from the settling tank. The trays are made of stainless steel AISI 304 and 316 and, unlike concrete trays, do not require waterproofing works and expensive repairs. This significantly reduces the operating costs of the company. Stainless steel trays are easily and quickly assembled, which reduces the cost of installation of sumps. It is also possible to change the configuration of the tray arrangement, for example, double-sided overflow trays can be installed.

Ring shields for the containment of floating substances

Keep grease, oil products and floating debris out of wastewater treatment plants. The semi-submersible shields are made of aggressive resistant stainless steel grades AISI 304 and 316 to enhance their performance and the simple design facilitates installation.

Center deflector

The deflector (stilling device) made of polymeric materials is characterized by high corrosion-resistant properties, reliability and a long period of trouble-free operation. The design of the deflector provides uniform distribution and direction of the flow, which in turn allows to increase the efficiency of separation of suspended solids and improve the quality of wastewater treatment.

Floatation screw collection device

An effective solution to improve the quality of wastewater treatment and float collection, recommended for a high proportion of industrial effluent or where conventional float removal systems fail. The auger device provides complete quality removal of floating matter from the sedimentation tanks water mirror, thus improving the quality of water treatment.

Half-and-a-half and diametral bridge

The application of half-and-a-half and diametral bridges in the design of primary and secondary settling tanks allows increasing: a) the quality of sludge removal from the bottom of the settling tank by increasing the number of bottom scrapers; b) the quality of floating matter collection by suspending an additional floating matter collection board on the whole truss of the diametral bridge. This solution is particularly effective for the treatment of wastewater with large amounts of floating matter and/or sludge.

Logarithmic scraper

A more rational solution to improve sludge removal efficiency and reduce operating costs. The shape of the scraper (single scraper from the side of the lagoon to the central pit) reduces sludge agitation during movement compared to conventional poly-scrapers. The logarithmic scraper allows the sludge to be moved from the extreme point of the sump to the pit in one revolution, which reduces sludge movement time and energy consumption.

Adjustable deflector (for primary sedimentation tanks)

A modern solution to improve the quality of wastewater treatment. The design of the deflector allows smooth adjustment of the speed and direction of the wastewater flow to ensure optimal parameters of the sedimentation process. This improvement is useful when flow rates and pollutants vary widely, which is typically the case when combined sewer and storm drainage systems are combined.

Bar set in primary sedimentation pits

An effective solution for sludge thickening and homogenization that significantly reduces the cost of subsequent transport, stabilization and dewatering. The use of bar bunding improves the quality of sludge thickening and reduces sludge moisture due to the removal of interstitial water from the sludge layers.
