SINOKLE Walnut Shell Filter: High-Efficiency Filtration Equipment for Oily Wastewater in Oilfields and Petrochemicals
In oilfield produced water, petroleum refining, petrochemical and various oily wastewater treatments, traditional filters often facepoor oil resistance, easy hardening, frequent backwashing, difficult regeneration and high maintenance costand other pain points, making it hard to meet the long-term stable filtration needs of oily wastewater.
Specially developed by SINOKLE for petrochemical and oily wastewater treatment,new-generation walnut shell filter, usingstrong adsorption, chemically stable, high-strength wear-resistantmodified walnut shell as filter media, achievingsimultaneous oil and suspended solids removal, easy regeneration by backwashing, and fully automatic stable operation, it is an ideal filtration equipment for deep treatment of oily wastewater in oilfields and petrochemicals.
I. Technical Core: Natural Wear-Resistant Filter Media,oil-resistant and easy toregenerate
The SINOKLE walnut shell filter usesspecially modified walnut shellas the core filtration medium, with four key characteristics:
Strong adsorption, large dirt-holding capacity: Porous structure and large specific surface area strongly adsorb oil droplets and suspended solids, with outstanding pollutant-holding capacity.
Oil-resistant, dual-effect removal: Resistant to oil soaking, simultaneously and efficiently removingoil and suspended solids, suited to high-oil wastewater conditions.
Chemically stable: Resistant to acid-base and corrosion, suited to complex water quality in oilfields and petrochemicals.
High-strength wear-resistant: The filter media is tough and wear-resistant, not easily broken during backwashing, with longer service life.
During filtration, sewage passes downward through the filter bed, and oil and impurities are efficiently intercepted and adsorbed; the backwashing processrequires no agentsto fully regenerate the filter media, and it can be used singly or in series, flexibly suited to different treatment scales.
II. Core Product Features
Strong adsorption, large dirt-holding capacity
The filter media has large specific surface area and abundant pores, with strong adsorption and interception of oil and suspended solids, and high treatment load.
Oil-resistant, dual removal of oil and suspended solids
Resistant to oil pollution, no hardening or oil-loving clogging, simultaneously achieving oil removal and suspended solids removal with stable effluent.
Easy regeneration, no agents in backwashing
Physical backwashing thoroughly desorbs oil and impurities, with good media regeneration effect,no backwashing agent needed, green and environmentally friendly.
Flexible combination, strong adaptability
Supportssingle-stage operationor multi-stage series, configurable flexibly according to treatment volume and water quality requirements, suited to various systems.
Fully automatic operation, remotely controllable
Supports on-site and remote automatic control, with automatic backwashing by pressure differential or time, stable operation and low labor cost.
