ECT Denitrification Filer System

The ECT denitrification and nitrogen removal technology is an advanced treatment process that inte- grates biological denitrification,micro-flocculation chemical phosphorus removal,and filtration for suspend- ed solids retention.It employs a downflow gravity deep-bed reactor design and utilizes next-generation air-water distribution technology.The biological media includes traditional materials such as quartz sand, bio-ceramic particles,and volcanic rock,as well as innovative options like composite biological media and proprietary glass media,which are energy-efficient and low-carbon.This technology is capable of handling various water qualities,offering high efficiency in TN and SS removal while being energy-saving and low-car- bon.With the simultaneous addition of PAC,it can also achieve stable compliance with TP standards.As a mainstream advanced treatment technology for enhancing the quality and efficiency of wastewater treatment plants,it produces effluent that surpasses the Grade 1A standard and local quasi-Class IV standards.It has been widely applied in municipal and industrial water treatment sectors.

■ Technical Feature Description

● This technology simultaneously removes TN,SS,and TP,and is adaptable to various tank structures,delivering ex- cellent treatment performance and highly stable effluent quality.

● The next-generation air-water distribution technology features a uniform chamber and four adjustable gaps,pro- viding more even secondary air-water distribution and load distribution,resulting in superior backwashing effects.

● The unique dual adjustable arc weirs at the inlet,combined with a stable hydraulic structure design,ensure better water distribution uniformity.

● The intelligent constant-variable water level automatic switching technology not only avoids dissolved oxygen los from water cascading but also ensures the longest filtration cycle,reducing operational costs.

● We offer a variety of filter media options,providing not only a stable deammonification environment but also a high SS interception rate of 55%.The deeper bed design reserves space for future secondary quality improvement and capacity expansion.

● A precise carbon dosing system,inteligent data analysis,and optimized operational conditions enable full-pro- cess intelligent control.
