Biosolids can be among the valuable resources recovered from clean-water plants. Yet, few operators would object to producing smaller volumes because the processing, handling and hauling cost money. Drylet, a wastewater remediation company, now offers a solution that, according to engineering reports, can reduce biosolids volumes by as much as half while also reducing chemical and energy costs and labor — all without capital investment.
There are various ways to produce Class A biosolids. Mark Bowman wants to prove to the Environmental Protection Agency that his preferred method is both cost-effective and scientifically reliable. Bowman, plant manager at the Gogebic-Iron Wastewater Treatment Facility in Ironwood, Michigan, faces challenges with the Class B cake his team now applies to cropland. One is dealing with regulations that require application at agronomic rates.
Not every clean-water plant operator can get paid for purposely upsetting the process or causing an equipment malfunction. Rick Lallish can — and often does. It’s part of his method as the Water Quality Control Operations program director at the Southern Illinois University Edwardsville Environmental Resources Training Center (ERTC). There, aspiring operators learn the trade on a 30,000 gpd activated sludge plant and a moving-bed bioreactor inside the center.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Musk AND Zuckerberg or Musk + Zuckerberg.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used). For example, results will contain either cake or cookie by searching cake OR cookie or cake,cookie
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
