ESEP

What ESEP does

ESEP Milieutechniek B.V. is a Dutch private limited company (B.V.) headquartered in Weert, Netherlands, with a regional office in Ham, Belgium, operating in environmental technology for more than 30 years since its founding around 1993. The company designs, manufactures, and supplies water treatment and management equipment, with a product portfolio that spans oil, grease, and sludge separators (in concrete and HDPE), coalescence filters, vortex flow controls (Wervelventiel) that operate without electricity or moving parts, pumping installations, sluice gates, non-return (check) valves in stainless steel and HDPE, screen filters, IBA/septic systems, and portable wash-water recovery and containment pads for defense use. Its proprietary technology stack is centered on KOMO- and CE-certified separators with internal HDPE lining for chemical resistance and durability, and on the Wervelventiel physical-principle flow controller, alongside stainless-steel gate and valve series compliant with European standards NEN-EN 858 and NEN-EN 1825.

The company sells through direct sales with expert consultation and site assessments (phone, email, contact form, physical offices in Weert and Ham), complemented by participation in major industry events such as IFAT Munich and listing in Dutch specification databases (NBD, STABU). Revenue is generated from two streams: (1) hardware sales of separators, vortex valves, pumping installations, sluice gates and related components, often as complete units with multiple capacity options, and (2) custom engineering and design services based on capacity calculations and customer-specific configurations. Named reference customers include one of the world's largest oil companies (delivery of 21 HDPE grease separators for gas station facilities), Belgian water authority Aquafin (four 4-meter stainless steel flushing gates for the Meerhout water storage basin), and the Dutch Ministry of Defense under the Fieldlab Smartbase Water initiative, where ESEP is developing portable wash and refueling containment pads with a stated target of 80% water recycling during international missions.

Products and services

• Oil Separators (Concrete) KOMO-certified (K2641) and CE-certified reinforced concrete oil separators for light mineral liquids, available in series KMI 6000 and KM 5000, designed for use in commercial, industrial, and automotive sites requiring compliance with NEN-EN 858.
• HDPE Oil Separators (Above- and Below-ground) Polyethylene oil separators with internal HDPE lining for chemical resistance and high durability, offered in above-ground and below-ground configurations, supplied to petrochemical and gas-station clients (e.g., 21 units of 4 l/s capacity conforming to NEN-EN 1825 delivered to one of the world's leading oil companies).
• Coalescence Separators Separators equipped with advanced coalescing filters for enhanced oil/water separation efficiency, intended for industrial and petrochemical sites where higher discharge quality is required or where effluent must meet surface-water discharge standards.
• Grease Separators (Concrete) KOMO-certified (K12925) reinforced concrete integrated grease separators for vegetable and animal fats (series KVI 4000), conforming to NEN-EN 1825, for restaurants, hotels, canteens, and food-processing facilities.
• HDPE Grease Separators Polyethylene and steel/stainless-steel grease separators for fats, oils, and grease removal in food-service and commercial kitchens, compliant with NEN-EN 1825.
• Sludge Separators and Sludge Traps Bezinkselafscheiders (settling separators), sludge traps (slibvanggoten), zandvangputten (sand catch pits), starch separators, gypsum separators, and dewatering containers for bentonite, sewer, and street-sweepings sludge, serving municipal and industrial pretreatment.
• Vortex Flow Controls (Wervelventielen) Proprietary passive hydraulic vortex valves (Wervelventielen) that limit water flow without electricity or moving parts.
