The future for using jet devices for solving environmental problems
The development of ejector technology is analysed as it applies for solving environmental problems. Success achieved in this field is connected with its special features the full absence of rotating and movable parts, lubricants and any seals and, consequently, the high reliability and low capital costs. This article concerns the use of jet devices for utilisation of steam obtained by means of ...

A good way to solve the sludge problem
Whether it is industrial sludge or municipal sludge, a feasible purpose of its treatment is to be returned to the process as raw materials. At present, the state has issued a number of policies to encourage sludge reduction, stabilization, harmlessness, and resource utilization. Reducing the water content of sludge is a way to reduce it, and it is also a prerequisite for resource utilization ...

Sustainable desalination technologies for future
This paper deals with some aspects concerning the dual objectives of cost-effectiveness and favourable environmental impact of desalination plants, resulting in a sustainable alternative source of fresh water for future needs. These include some case studies on the use of waste heat for the thermal desalination plants, replacement of conventional pre-treatments in membrane plants with cleaner ...

Introduction of Solar Drying Technology to Trinidad and Tobago
A review of the existing solids management practices in Trinidad and Tobago and experience elsewhere defined the future needs and identified solar drying as a preferred technology for the subject project. Upon analysis of the local conditions, it was calculated that approximately 19 MJ/m2 (1886 kWh/m²) of solar radiation, at 30ºC annual average temperature and 80% relative humidity ...

Status and future development of sludge drying technology
Sludge drying is the process of removing most of the water in the sludge through evaporation and other actions. The types of drying mainly include solar drying, thermal drying, ultrasonic drying, microwave heating drying and biological drying, among which sludge thermal drying technology is the most widely used and mature technology. The heat transfer medium used in the sludge thermal drying ...

The impact of technology on the environment and how environmental technology could save our planet
This article takes a look at the paradoxical ideology that while the impact of technology on the environment has been highly negative, the concept of environmental technology could save our planet from the harm that has been done. This idea is supported by WWF 1, who have stated that although technology is a solution enabler it is also part of the problem. The term ‘technology’ ...
