Wick type solar stills: A review

Solar distillation is one of the water purification techniques that produce ultrapure water which is superior to most of the commercial bottled water sources. Though solar distillation is a simple method, productivity seems to be low due to the large thermal capacity and consumption of time. Researchers have taken efforts to make different designs of solar still for higher distillate yield and inferred that wick-type solar stills are effective and efficient. In this review, we are making an attempt to study the present status of different designs of wick type solar stills.
