Integrated Solutions of Filters & Breathing Valves

Liquid Filters for Sewage & Wastewater

Applications：Inlet water of sewage treatment, biochemical effluent, reclaimed water reuse, sludge pre-treatment, chemical dosing systems.

Matching Solutions:Basket filters, self-cleaning filters, bag filters, precision security cartridge filters.

Exhaust Air Filtration for Workshops & Plants

Applications:Ventilation of hazardous waste warehouses, chemical workshops and laboratories.

Filtration Scheme:Combination of primary filter + medium efficiency filter + activated carbon filter, realizing dust removal and odor elimination to meet emission standards.

Common Types of Environmental Protection Breathing Valves

All-Weather Breathing Valve: Suitable for ordinary storage tanks, sealed sewage tanks and wastewater equalization tanks. It maintains constant pressure ventilation and prevents odor diffusion.

Flame Arresting Breathing Valve: Applied to storage tanks of gasoline, diesel, organic solvents and hazardous chemicals. Integrated breathing and flame arresting functions for explosion protection and safety.

Breathing Valve with Connecting Pipe: Concentrate discharged waste gas through pipelines and guide it to waste gas scrubbers for organized collection and treatment, specially designed for environmental acceptance inspection.

Breathing Manhole: For large-scale sealed sewage tanks; prevents tank collapse caused by negative pressure and bulging under positive pressure.

Combined Matching Solutions of Filters and Breathing Valves

Solution 1: Covered & Sealed Sewage Tank System

Configuration: Pipe-connected breathing valves installed on tank tops, plus pre-installed dust filters on waste gas pipelines.

Working Flow: The breathing valve stabilizes pressure and blocks odor → waste gas is centrally collected → dust is removed via pre-filtration by filters → gas is conveyed to spray towers or activated carbon adsorption units for treatment.

Solution 2: Environmental Supporting Package for Chemical Tank Farms

Configuration: Flame arrester breathing valves, matched with basket filters or precision filters on waste gas branch pipes.

Advantages: Explosion-proof and flame arresting performance, constant-pressure ventilation, impurity interception, and blockage prevention for waste gas treatment equipment.

Solution 3: Front-end Filtration for Spray Towers & Waste Gas Treatment Equipment

Configuration: Primary filters at air inlets + wire mesh mist eliminator filters inside the tower.

Advantages: Dust removal at the front section and mist elimination at the rear section; protects fans, lowers maintenance costs, and ensures stable compliance with emission standards.
