What HYGIA does

HYGIA (full legal name: 山东海吉雅环保设备有限公司 / Shandong Haijiya Environmental Protection Equipment Co., Ltd.) is a privately held Chinese environmental-protection equipment manufacturer founded in December 2003 and headquartered in Tengzhou Economic Development Zone, Shandong Province. The company designs and builds water and wastewater treatment systems with a primary focus on oilfield produced-water treatment, complemented by sludge reduction, drilling/workover waste liquid handling, and municipal/domestic wastewater equipment. Its factory sits on a 55,000 m² site with 11,000 m² of modern workshops and 11 overhead cranes (5t/10t/20t), generating stated annual capacity above 100 filter-unit sets and reported output value above 50 million yuan per year.

The company's technical anchor is a proprietary physical (non-chemical) treatment process embodied in its DYTL-series skid-mounted, multi-functional integrated oilfield water treatment device. The unit integrates turbulent flotation oil removal, micro-vortex pollutant/turbidity reduction, filtration purification, desulfurization, iron removal, electrode-based scale prevention and corrosion inhibition, sterilization, and filter-medium vortex backwash regeneration, operating under PLC-based automatic control. The physical method eliminates chemical dosing, cuts sludge output by more than 50%, and reduces pipeline corrosion by more than 90% versus conventional chemical multi-stage processes. The proprietary technology is supported by 30+ granted patents (11+ invention patents, 21+ utility models), a 2020 Shandong Provincial Science and Technology Progress Award, a 2013 National Key New Product designation, and a 2010 Shandong First-Set Technical Equipment recognition.

HYGIA sells predominantly through direct enterprise field sales to Chinese state-owned oil majors (Sinopec, PetroChina, CNOOC subsidiaries such as Shengli, Zhongyuan, Henan, Jidong, Changqing, Dagang, Jianghan, and Yanchang Petroleum) by winning public procurement bids and framework agreements, supplemented by international direct sales (Congo Djeno, Indonesia/Pertamina, Oman, Russia, Canada) and an equipment rental model (e.g., Jianghan Oilfield 300 m³/d and Jidong Oilfield He50 platform 2,400 m³/d rentals). Revenue streams include hardware sales (treated water equipment, sludge reduction equipment, filter presses, integrated municipal/domestic systems), installation and after-sales technical services, BOT/turnkey project management, and the rental channel. The company has expanded beyond oilfield water treatment into sludge reduction equipment (electro-osmotic dewatering, stacked spiral dewatering machines, low-temperature dryers), a planned 600 million yuan solid-waste treatment equipment project listed as a provincial major project, and a 2021 industrial-robotics joint venture (Shenkong Shandong Robot Technology), which collectively suggest broader industrial-environmental ambitions beyond the original oilfield niche.
