The purpose of this novel design is to provide a type of automatic floating debris or aquatic plant barrier for river channels, which can automatically remove floating debris or aquatic plants within the river. This not only eliminates the need for substantial human and material resources for cleaning but also prevents the accumulation of floating debris or aquatic plants, significantly shortening the cleaning cycle and avoiding secondary pollution.
Self-floating river automatic pollution barrier device, including a concrete construction platform located on the left bank of rivers and lakes, a floating debris treatment pond situated on the right bank and downstream of the concrete construction platform, as well as steel cable fixed concrete piers spanning across both banks of the river, linking individual pollution barrier buoys together through the cables to form a parabolic overall pollution barrier. When there's excessive underwater garbage, the buoys can also be combined by clamping steel plates and weaving a net, achieving a vertical effect through galvanized underwater ballast. This solution offers exceptional pollution barrier performance, effectively managing both surface and underwater garbage, preventing the spread of surface garbage, and has received high praise from customers after the Zhejiang Tianwei new type of pollution barrier buoy scheme was launched into the market.

Sewage screen floats are gaining popularity due to their excellent impact, performance, and reasonable pricing. What's more important is their minimal environmental harm and low maintenance requirements. Whether in deep or shallow water, moving or still, saltwater or freshwater, cold or hot, clean or polluted water, almost anywhere there's water, these floats can be put to good use. Products made from these floats offer endless variety, can be freely combined into various shapes, are easy and quick to install and dismantle, cause minimal environmental harm, are lightweight, stable, and safe, and require no maintenance.

This product features a *tough and aging-resistant ring* design, made of PE material, formed through rotational molding and naturally cooled, preserving the original strength and properties of the plastic. Enhanced with expanded polystyrene foam, similar to foam material, for filling, it achieves the benefits of light weight, high buoyancy, long service life, and low cost. It has been applied in various fields and received unanimous praise! Raw Material: Imported *LLDPE (low-density polyethylene) has been widely used for river swimming and recreational activities since summer, with drowning incidents occurring annually. After relevant departments approached Tianwei Company, our proposed solution was to use our 30cm diameter mirror-like floating balls, available in three colors (yellow, red, white) spaced every 2 meters. Since their installation in early summer, they have not only not affected everyone's enthusiasm but have also become a beautiful sight, prompting nearby tourist areas to follow suit!

Water Pollution Control Equipment, a new eco-friendly product developed by Tianwei Company, is designed to address floating debris such as plastic bags, bottles, and paper fragments on water surfaces. It features a small floating barrier to contain the waste, starting pollution control at its source. It can be installed and deployed upstream of rivers, at reservoir inlets, in lakes, before the trash racks of hydroelectric power stations, and in moats, etc. It is particularly suitable for water source pollution warning barriers, fish farming area waste containment, and isolation. Tianwei's maintenance-free floating barriers can encircle all debris in a specific area, making cleanup and collection easier and more time-efficient, ensuring a clean water surface after treatment. The floating barriers can be produced in various colors to match the environment.
Ningbo Tianwei Plastic Technology Co., Ltd. boasts advanced rotational molding production technology, catering to market demands. Through the meticulous efforts of our R&D department, we have developed multiple models of plastic debris boom with high-grade materials. The products are integrally formed with a smooth surface, filled with PU foam plastic inside, offering high buoyancy, acid and alkali resistance, corrosion resistance, impact resistance, and excellent pressure resistance. The buoyant bodies are made of high-density synthetic materials, enhanced with anti-freezing, anti-aging, and anti-UV properties, and are immune to corrosion from seawater, chemicals, pharmaceuticals, oil stains, and aquatic organisms. They are environmentally friendly, causing no pollution, and do not harm the environment.
