The operation of an Automatic Backwashing Filter involves a systematic process for continuous and efficient filtration: Inlet and Outlet Ports: Unfiltered fluid enters through the inlet port, while the filtered fluid exits through the outlet port. Filter Media: Materials like sand or activated carbon capture impurities and particles from the incoming fluid.
Continuous Contact Filtration Process which combines coagulation, flocculation and filtration in one operation Flocculation and settling basins are eliminated ahead of the filters Floc forms quickly when pumping energy is dispersed in the sand bed Pin point flocs are formed Coagulant dosage reduced by 30% DynaSand®Filter
The Hydrasand continuous sand filter is an economical sand filter for continuous cleaning of sand to achieve efficient effluent cleaning.
The DynaSand ® EcoWash ® Filter expands upon the DynaSand platform by allowing continuous filtration with intermittent sand washing. Operating in this mode, the system reduces the amount of reject water, increases filter performance, maximizes the airlift life cycle, and reduces maintenance time.
The SuperSand continuous backwash sand filter is an up-flow moving bed filter that is constructed with various media depths for different applications and configurations.
The first stage filter uses larger sand grain size to give it more solids-handling capacity, and employs a proprietary DynaSand® process known as Continuous Contact …

Continuous Backwash Filters. Continuous back wash sand filter is a simple, efficient and easy-to-manage filtering device. Compared with the traditional quartz sand filter, it integrates flocculation, clarification, and filtration.
The DynaSand® EcoWash® Filter allows continuous filtration with intermittent sand washing. Operating in this mode, the system reduces the amount of reject water, increases filter performance, maximizes the airlift lifecycle, and reduces maintenance time.
The DynaSand® filter is an upflow, deep bed, granular media filter with continuous backwash. The filter media is cleaned by a simple internal washing system that does not require backwash pumps or storage tanks. The absence of backwash pumps means low energy consumption. The DynaSand filter's deep media bed allows it to handle high
Overview. The Moving-bed Sand Filter is an upflow-type continuous sand filter. Since water filtration and sand washing can be performed simultaneously, continuous filtration is possible.
The continuous backwash sand filter MONASAND® provides a continuous filtrate production, without requiring periodic stops for sand cleaning. It ensures highquality liquid/solid separation by efficiently removing suspended fine particles. Additionally, it distinguishes itself with low water and energy consumption.
The DynaSand® EcoWash® Filter allows continuous filtration with intermittent sand washing. Operating in this mode, the system reduces the amount of reject water, increases filter performance, maximizes the airlift lifecycle, and reduces maintenance time.
The dirty sand is continuously removed from the active sand bed (A) thanks to the action of the air-lift pump (C), which sucks the contaminated sand from the bottom (B) of the filter body. A mixture of sand, dirty particles and water is transported upward through the air-lift pipe into the washing chamber at the top of the filter.
These WASH-related diseases can be controlled with adequate access to safe water, proper sanitation, improved hygiene, ... Table 1 provides some typical characteristics of continuous-flow slow sand filters that are consistent with the numbers provided above regarding typical hydraulic retention times. Table 1.
The SuperSand continuous backwash sand filter is an up-flow moving bed filter that is constructed with various media depths for different applications and …
As the sand falls through the washer, a small amount of filtered water passes upward, washing away the dirt, while allowing the heavier, coarser sand to fall through the bed. The wash water, which consists in a certain amount of filtrate water and separated solids, exits near the top of the filter.
The Siebtechnik Tema Continuously Washing Up Flow (CWUF) sand filters are deep bed gravity filters that continuously self-clean during operation.
Sand filters can be operated with either upward flowing fluids or more commonly downward flowing fluids. For downward flowing devices, the fluid can flow under pressure or by gravity. ... The continuous flow of reject washing water is discharged through a separate outlet. Downloads for Filter Backwash. Trusted Experts.
DynaSand Continuous Sand Filters. The DynaSand filter is a compact filter without moving parts. No rinsing water supply tanks, sludge water tanks, rinsing pumps or automatic backwashing systems are required. To get more information please expand the product block by pressing on image or product title.
The continuous filter is a kind of sand filter, which will operate without any interruptions for backwashing and also it accepts high-suspended solid levels in feed stream.
adjustable s with a uniquely designed wash box will allow operators to optimise the sand washing rate (sand to water ratio), thus minimizing the backwash wasting rate. continuous improvement ...

The ASTRASAND TM filtration system is a new and improved continuous sand filter, developed for physical-chemical and/or biological treatment of different types of water, such as process, waste, surface, cooling and ground water.
The sand washing device of the continuous sand filter is different from the filter in the past. Its length is longer and the angle of the sand washing ring varies from top to bottom. Therefore, a small amount of washing water can achieve a good cleaning effect. The reason why the washing water can flow
In order to avoid this drawback, we need to allow for a system that holds the filter matter in place (e.g. a grating…) or to select a homogenous sand, continuous wash filter. floating bed filters (figure 42)
