Grease and hydrocarbon separators for car washes, parking lots, gas stations and industrial applications. Compliant with environmental legislation.
In short · updated
Weldplast Technology is a Romanian manufacturer of plastic separators, with a workshop in Cârcea (Dolj): EN 858 hydrocarbon separators, Class I or II, for fuel stations, car parks, workshops and car washes, and grease separators sized by NS to EN 1825 for restaurants, hotels, canteens, slaughterhouses and meat processing. Every separator is made to order in PE-HD or PP-H, for flows of 0.5-100 L/s, with sludge trap, coalescing filter and bypass as the project needs. For a quote, send the flow, the water source and the permit requirement to sales@weldplast.ro or call +40 729 542 142.
For hotel kitchens, guesthouses, restaurants, slaughterhouses and meat processing plants, sized by nominal size NS according to EN 1825.
Mandatory for gas stations, parking lots, auto services, mechanical workshops and car washes.
The class is selected from the discharge limit in the permit, with the sludge trap and separation equipment required by the project.
Bypass systems for high flow rates and overflow valve for overload situations.
Ecological Solutions

Major project of 240 WELD eco septic-tank units. 3,750 L and 10,000 L capacities for rural infrastructure.

Hydrocarbon separator with coalescent filter, BW filter and 4l/s bypass. Complete solution for gas stations and parking lots.

Weld eco-friendly septic tank with three chambers, 28,000 liter capacity for efficient wastewater treatment.

First delivery from a 200-unit septic-tank order.

70 L/s hydrocarbon separator delivered in Transylvania.

Eco-friendly Weld septic tanks for infrastructure applications.
Yes. Weldplast Technology builds hydrocarbon separators in PE-HD or PP-H in its Cârcea (Dolj) workshop, to EN 858-1 and EN 858-2. Class I or II follows the discharge limit in the permit, and the separator gets a sludge trap, coalescing filter and bypass as the project needs. Every unit is made to order, for flows of 0.5-100 L/s.
A grease separator is sized by its nominal size (NS) to EN 1825, from the kitchen's flow, water temperature, fats and detergents used, and working hours. We build them to order for restaurants, hotels, guesthouses, canteens, slaughterhouses and meat processing, for wastewater up to 60 °C. Send us the meals per day or the connected equipment and we work out the right NS.
The price depends on the flow, the class or NS, the installation depth and the fittings, so there is no fixed price list. Send the flow, the water source and the permit requirement and we send you a firm quote.
For a hydrocarbon separator: the application (car park, fuel station, car wash), the drained area or design rainfall flow, the wastewater flow, the detergents used and the permit requirement. For a grease separator: the type of business, the meals per day or connected equipment, the water temperature and the installation site. Send them to sales@weldplast.ro or call +40 729 542 142.
