Tertiary Cloth Filters | Evergreen Water Solutions
Improving final effluent quality by removing suspended solids (TSS) and nutrients (TP) can be a challenge.
With higher quality effluent standards from the Environmental Agency (EA), we work closely with UK and Ireland water utility companies and industrial clients to meet the highest effluent standards Our tertiary cloth filters can treat secondary treated effluent to 0.2mg/L of Total Phosphorus in a single pass.
Our cloth filters remove total suspended solids (TSS) and total phosphorous (TP) in final effluent for the industrial and municipal wastewater plants.
Horizontal Tertiary Cloth Filters
The result is final effluent with significantly reduced levels of suspended solids and nutrients including total phosphorous. Particulates of iron (FE) and microplastics are removed from the water simultaneously. The cloth filters design comprise of a series of cloth filter discs installed in a hexagonal array around a hollow central shaft. The secondary treated effluent to pass through from the outside of the filter cloth to the inside of the cloth by gravity alone. The microfibre cloths remove suspended solids (TSS) in the wastewater down to 5micron.

The key element of the filtration capability lies within the filter cloths. The pile cloths are an advanced synthetic fabric of microfibres which trap suspended solids, whilst allowing the filtered effluent to flow onward toward the filter outlet.
The cloths are cleaned automatically during a backwash cycle operated by differential level or on a timer control. During the back wash cycle, the filter discs and shaft rotates at 1-2rpm, while a series of backwash pumps connected to fixed nozzle per disc cleans the trapped solids from the filter cloth.
The cloth filter machines will continue to filter TSS uninterrupted while initiating a backwash cycle and clean up to eight (8) filter discs at any one time with dual backwash pump. The nozzles are positioned against the disc face and create a powerful suction provided by the back wash pumps allowing treated effluent from the clean side of the cloth to remove the solids from the cloth face.
This suction draws trapped solids on in the pile cloth away from the cloth surfaces; maintaining the normal passage of filtered flows. The backwash operation allows the filter to continue filtration during its cycle, significantly minimizing plant down-time.
Industrial Cloth Filters for the Treatment of Wastewater
The benefit of this automatic and continuous filtration product is exemplary, long-life tertiary filtration performance, with low initial investment, and O&M costs.
The filters are available in either a horizontal or a vertical configurations, with backwash pumps installed either internally or externally. The vertical filters also offer the ideal solution for ‘Plug-and-Play’ site filtration requirements.
A small footprint inherent to their design, combined with the option to select filters with a series of 2-32 discs allows a high range of scalability depending on site requirements.
Evergreen Water Solutions offers our client bespoke system solutions. Our tertiary filtration package reflects this customisation by providing options to supply various configurations including dual pass cloth filter systems with upfront flocculation.
Along with all required electrical instrumentation, control and automation and process plant integration.
Phosphorous Reduction
With the combination of our Pile Cloth Disc Filter and Microfiber Filter Cloth, we achieve a remarkable reduction in total phosphorus levels to below 0.2 mg/l, tailored to the specific inlet conditions. This powerful combination exemplifies our commitment to advanced water treatment, ensuring environmental sustainability and purity in wastewater management.
TSS Reduction
In a recent case study, our Pile Cloth Disc Filter demonstrated its exceptional capabilities by reducing Total Suspended Solids (TSS) from a high concentration of 743 mg/l to an impressively low 3.8 mg/l, achieving an outstanding 95% reduction. This remarkable performance underscores the effectiveness of our advanced filtration technology in transforming wastewater quality.
NTU Reduction
Our Pile Cloth Disc Filter, in collaboration with our Microfiber Filter Cloth, achieves significant NTU reduction, bringing levels down to approximately 2 depending on the influent conditions. This powerful combination ensures optimal clarity in treated water, emphasizing our commitment to delivering high-performance solutions in water filtration.
Hydraulic Load
The hydraulic loading of our Pile Cloth Disc Filter is carefully optimized to balance efficiency and performance, allowing for a seamless flow rate that ranges from 5 to 15 m/h. This ensures an optimal balance between water treatment capacity and effective filtration, making it a versatile solution for various wastewater treatment applications.
