What Sanshine China does

Sanshine China (Jiangsu Sanshine Environmental Protection Technology Co., Ltd. / 江苏三辉环保科技有限公司) is a privately-held Chinese high-tech manufacturer founded in April 2015 in Jiangyan District, Taizhou City, Jiangsu Province. The company designs, manufactures, and sells solid-liquid separation equipment — primarily stacked-screw sludge dewatering machines (HDL series), swing-screw dewatering machines (HYP series), hammer-mill dewatering machines (SL series), screw-press dewatering machines, and disc microfilters — alongside complementary vertical fiber filter cloth basins, drum precision filters, spiral screens, inclined plate settling tanks, extrusion solid-liquid separators (livestock manure), sludge drying equipment, dosing devices, spiral conveyors, and water treatment chemicals. Its proprietary architectures were co-developed with Tongji University (flat-jet sludge discharge system) and Fudan University's national laboratory (SP vertical fiber filter cloth basin), the latter receiving the Ministry of Science and Technology '11th Five-Year' National Major Science and Technology Achievement Recommendation.

The company serves 12+ industry verticals including municipal wastewater treatment, food and beverage, paper manufacturing, electronics, chemicals, petrochemicals, steel, paint and coatings, mining, pharmaceuticals (including an AstraZeneca Taizhou installation), aquaculture/slaughter, printing/dyeing, electroplating, and kitchen waste processing. Headcount is reported at 251–500 employees. Named installations span municipal plants (e.g., Huangpi New Wuhu Waterworks, Shanghai Chongming Chenjia Town), universities (Xiamen University), and enterprise accounts (Yunnan Dashan Beverage, Wuhan Renfu Pharmaceutical, Henan Hebi Tianma Communication, Anhui Quansheng Chemical, Papua New Guinea nickel-cobalt tailings project, Malaysia municipal wastewater plant).

Sanshine employs a direct sales model with field sales teams covering industrial sectors, supplemented by a dedicated sales office in Yixing, a 24-hour service hotline, and an extensive trade-show strategy (9+ major domestic and international exhibitions in 2023, including IFAT Munich 2024, Aquatech Amsterdam, VIETWATER Vietnam, Indo Water Indonesia, and multiple Chinese environmental expos). Revenue is generated primarily through one-time capital equipment sales, engineering solutions and after-market technical services, and complementary chemical sales. Pricing is quote-based and not publicly disclosed. The company exports selectively to Southeast Asia, Europe, and other regions via project-based international sales rather than established overseas distribution.
