Treating highly emulsified wastewater from heavy fuel oil (HFO) power plants is a universally recognized industrial challenge due to high oil concentrations (up to 2,000 mg/L) spanning vast oil droplet size distributions. In a textbook case study under Bangladesh's BR Powergen Limited, Shenzhen Clear Science & Technology Co., Ltd (SINOKLE) successfully bridged the gap between principle-level design and engineering implementation. The project deploys an innovative, chemical-free process chain combining primary cyclonic centrifugal separation, secondary ultra-micro bubble flotation with physical coalescence demulsification, and deep-bed KFM Activated Filter Media filtration. By systematically distributing loads across optimized stages without chemical reliance, this skid-mounted system permanently lowers operational costs and hazardous waste burdens, stably reducing influent oil from 2,000 mg/L to an impressive effluent level of below 10 mg/L.2026/07/17
Managing complex oily wastewater in oilfields and petrochemical refining presents intense environmental compliance challenges. Addressing this industry-wide headache, Shenzhen Clear Science & Technology Co., Ltd (SINOKLE) developed an integrated, chemical-free solution combining its patented Two-Stage CDFU (Cyclonic Dissolved Gas Flotation) technology and KFM Activated Filter Media filtration. The system uses a high-speed tangential cyclonic flow field paired with 5–30 micron micro-nano bubbles to physically strip out over 99% of floating, dispersed, and emulsified oil. This effluent then passes through the KFM filter—a silicate media modified via Atomic Layer Deposition (ALD) boasting 300 times the surface area of quartz sand and a 15-year service life—for precision 1-micron polishing. Operating with zero chemical dosing and full nitrogen blanketing to contain volatile organic compounds (VOCs), this automated, skid-mounted process reduces effluent oil below 5 mg/L and suspended solids below 1 mg/L, meeting the most stringent oilfield reinjection and industrial reuse standards.2026/07/10
In celebration of the Dragon Boat Festival, Shenzhen Clear Science & Technology Co., Ltd (SINOKLE) shares a warm, poetic message of peace, health, and mindfulness for its clients, partners, and employees. Reflecting the natural renewal of midsummer, the company encourages everyone to step back from the fast-paced corporate world to find moments of quiet comfort with their families. Embracing its core commitment to long-term well-being and smooth paths ahead, the entire team at SINOKLE extends its warmest wishes for safety, prosperity, and joy during this traditional holiday and for all the days to follow.2026/06/18
The stable presence of micron-sized emulsified oil droplets (< 20μm) presents a notorious bottleneck in industrial wastewater pretreatment, where traditional gravity tanks fail and chemical demulsifiers spike hazardous sludge disposal costs. Directly addressing this challenge, Shenzhen Clear Science & Technology Co., Ltd (SINOKLE) developed the KHC High-Efficiency Coalescing Oil Separator. By utilizing atomic layer deposition (ALD) to engineer a super-hydrophilic coalescing media (water contact angle < 10°), the KHC system increases organic anti-fouling by 90% and forces emulsified oil droplets down to 0.1μm to physically collide and coalesce. Operating at a minor pressure drop (< 0.05 MPa) with zero chemical dosing, this automated, skid-mounted device consistently reduces effluent oil concentrations below 10 mg/L while providing 3 to 5 times the cross-sectional flux of conventional separators.2026/07/02
