Harlequin CAP18: Compact and Efficient Sewage Treatment

Introducing the Harlequin CAP18, a state-of-the-art sewage treatment plant designed for domestic installations, capable of serving up to 18 inhabitants. This innovative Continuous Aeration Plant boasts a 96.2% pollutant removal level, making it an ideal choice for ensuring environmental compliance while maintaining a high standard of living. The CAP18's unique bio-media system eliminates common issues found in smaller treatment plants, providing a reliable and efficient solution for domestic use. With its compact size and lightweight design, it is easy to install and maintain, making it a perfect fit for homes and properties with up to 6 inhabitants (4 bedrooms). The Harlequin CAP18 is a testament to Harlequin's commitment to delivering high-quality, durable, and eco-friendly sewage treatment solutions.

Product Specifications and Technical Details

The Harlequin CAP18 is crafted from durable medium density polyethylene material, ensuring longevity and ease of maintenance. It features 110mm inlet and outlet connections, integrated lifting eyes for convenient handling, and a 450mm pedestrian duty, flush fitting manhole cover. The above-ground air blower housing enhances reliability and accessibility for maintenance. The CAP18 operates virtually silently, thanks to its near-silent air compressor housed beneath the flat lid. This system is mechanically reliable, with no moving parts or electrics within the tank, and is certified to EN12566-3, meeting the highest industry standards. Key specifications include a maximum hydraulic load of 2700 liters/day, an organic load of 960 g BODs/day, and an empty plant weight of 600 kg. The system requires desludging every 12 months and is designed to serve a population of 16 to 18 individuals.

Benefits and Applications

The Harlequin CAP18 offers numerous benefits for both homeowners and property managers. Its compact size and lightweight design reduce installation costs and make it an ideal solution for small to medium-sized domestic properties. The easy maintenance aspect of the CAP18 is a significant advantage, as it only needs to be emptied every 12 months, and the compressor is easily accessible for maintenance. The system's low noise operation ensures that it will not disturb the peace and quiet of your home. With its high pollutant removal rate and eco-friendly design, the CAP18 is an excellent choice for those looking to reduce their environmental impact while enjoying the comfort and convenience of a modern sewage treatment solution. This product is particularly suitable for homes, cottages, and other domestic properties where space is limited and efficiency is key.
